Methods and devices for adjusting resource management procedures in heterogeneous communication networks

Abstract

Devices and methods for adjusting resource management procedures in heterogeneous communication networks are disclosed. In one aspect, a method for adjusting radio resource management procedures in a mobile device communicating with a node operating in a cell in a heterogeneous communication network includes receiving a message that includes cell information transmitted from the node, measuring signal reception information, processing the received cell information and measured signal reception information to determine an adjustment to a resource management procedure, and adjusting the resource management procedure based on the determined adjustment. The first and second messages may be radio resource control (RRC) measurement control messages.

What is claimed is: 
     
       1. A method for adjusting resource management procedures in a mobile device communicating with a node operating in a cell in a heterogeneous communication network, the method comprising:
 receiving, by the mobile device, a message transmitted from the node, the message including cell information; 
 measuring, by the mobile device, signal reception information; 
 processing, by the mobile device, the received cell information and measured signal reception information to determine an adjustment to a resource management procedure; and 
 adjusting, by the mobile device, the resource management procedure based on the determined adjustment, 
 wherein the resource management procedure is a radio resource management procedure, 
 wherein adjusting the radio resource management procedure includes adjusting one or more of handover, uplink (UL) power control, radio link failure (RLF) recovery and link adaptation, 
 wherein adjusting handover includes one or more of setting the size of a measurement report, setting a value of a measurement gap, determining a Time-to-Trigger value, and determining a signal hysteresis value, 
 wherein the received cell information includes information relating to cell size and system load, the radio resource management procedure includes setting the size of a measurement report for transmission to the node, and 
 wherein, based on the cell size and system load, the size of the measurement report is adjusted to a standard size or a minimum size. 
 
     
     
       2. The method of  claim 1 , wherein the message is a radio resource control (RRC) measurement control message. 
     
     
       3. The method of  claim 1 , wherein the cell information includes information relating to one or more of cell size, cell type, system load, node information, maximum transmit power, maximum base station users, number of antennas and antenna gain. 
     
     
       4. The method of  claim 1 , wherein the signal reception information includes information relating to one or more of reference signal received power (RSRP), reference signal received quality (RSRQ), channel quality indicator (CQI), channel state information (CSI), and signal to interference plus noise ratio (SINR). 
     
     
       5. A mobile device operable in a heterogeneous communication network to transmit messages to and receive messages from a node operating in a cell, comprising:
 a processor; 
 a memory coupled to the processor; 
 a transceiver coupled to the processor; and 
 an antenna coupled to the transceiver configured to transmit and receive messages; 
 wherein the processor is configured to:
 receive a message transmitted from the node, the message including cell information; 
 measure signal reception information; 
 process the received cell information and measured signal reception information to determine an adjustment to a resource management procedure; and 
 adjust the resource management procedure based on the determined adjustment, 
 wherein the resource management procedure is a radio resource management procedure, 
 wherein adjusting the radio resource management procedure includes adjusting one or more of handover, uplink (UL) power control, radio link failure (RLF) recovery and link adaptation, 
 wherein adjusting handover includes one or more of setting the size of a measurement report, setting a value of a measurement gap determining a Time-to-Trigger value, and determining a signal hysteresis value, 
 wherein the received cell information includes information relating to cell size and system load, the radio resource management procedure includes setting the size of a measurement report for transmission to the node, and 
 wherein, based on the cell size and system load, the size of the measurement report is adjusted to a standard size or a minimum size. 
 
 
     
     
       6. The mobile device of  claim 5 , wherein the message is a radio resource control (RRC) measurement control message. 
     
     
       7. The mobile device of  claim 5 , wherein the cell information includes information relating to one or more of cell size, cell type, system load, node information, maximum transmit power, maximum base station users, number of antennas and antenna gain. 
     
     
       8. The mobile device of  claim 5 , wherein the signal reception information includes information relating to one or more of reference signal received power (RSRP), reference signal received quality (RSRQ), channel quality indicator (CQI), channel state information (CSI), and signal to interference plus noise ratio (SINR).
